About These Birds
Atitlan Grebe
Atitlan Grebe (Podilymbus gigas) is an extinct large flightless grebe formerly endemic to Lake Atitlán, Guatemala. Similar to Pied-billed Grebe but larger, with heavier bill and flightless wings. Extirpated by the 1980s due to introduced bass predating chicks, reed-bed destruction, and hunting. Last confirmed individuals died in the early 1990s.
Titicaca Grebe
Titicaca Grebe (Rollandia microptera) is a large 28–45 cm flightless grebe endemic to Lake Titicaca on the Peru-Bolivia border at 3,800 m elevation. Brown with rufous neck; greatly reduced wings. Largest of its genus. Endangered; population ~2,000 birds; declining from gill-net drowning, egg collection, and reed-bed reduction. IUCN Endangered.
